# 天王级LayerZero丐版超低成本保姆级交互（跨6条链，5个桥）一鱼多吃 By [Lin Dora @duola_eth](https://paragraph.com/@lin-dora-duola-eth) · 2023-04-15 --- 作者：Lin Dora 推特：[@Taiyanghuaaa](https://twitter.com/Taiyanghuaaa) 前言篇： We Are Flowers 已经上线[opensea](https://opensea.io/collection/we-are-flowers),0版税，笑脸拯救世界。 喜欢的朋友可以去mint一个，目前地板价0.018e,项目方要做到0.5e一个。 项目篇： LayerZero是一种全链互操作性协议，专为跨链的轻量级消息传递而设计。LayerZero 提供了可信且有保障的消息传递，并具有可配置的去信任化。 先后融资了2.61亿美金，投资阵容相当豪华，A16z,Coinbase等等。 ![](https://storage.googleapis.com/papyrus_images/624ba8fc7f74e7c2dc54dc85a03ce8e14a7f9ffd408932040d46572524bfca6a.png)

LayerZero号称全链互操作性协议，所以重点就在一个跨链的操作。 首先说明，我这篇教程不打算做精品账号，但是你也可以听听我的思路，或许对你也有帮助。 教程开始前，我先做个简单的目录吧，因为这个确实需要跨的链太多了，其中还有个测试网的。 **需要跨的链有：Arbitrum-ETH，Optimism-ETH，Avalanche-AVAX，BNB-BNB，** **Polygon-MATIC，Fantom-FTM，还有USDC。** **需要先提前充值好对应的GAS。Fantom** 用到的桥：Stargate，bungee，jumper，[BTC.b](https://bitcoinbridge.network/)，[USDC](https://usdcdemo.layerzero.network/)，[Testnet](https://testnetbridge.com/) 其中bungee，jumper都有融资，还没有发币，我们都可以交互下，做到一鱼多吃。 至于后面的[Aptos](https://theaptosbridge.com/)的还有NFT之类的我不打算做了，毕竟我做的就是一个丐版的交互。 教程开始： **1.Stargate跨链，在这边我们要跨6条链** [ Bridge USDC, USDT, ETH, BTC & OFTs Across Chains | Stargate Finance
